The three recorded an episode together and talked about their 'Produce 101' behind stories. Lee Suk Hoon confessed, "My wife's favorites were Baekho, Ong Seong Wu, and Kang Daniel. I told Baekho straight up, 'I don't like you'."

Baekho added playfully, "He told me that when I was having the hardest time during dorming." However, he got to have revenge on his former teacher with more vicious comments during the 'Happy Together 3' episode.
